Ingredient profile
Ginseng and eleuthero in Glyco Harmony
Glyco Harmony lists two ginseng-type herbs: eleuthero root at line 5 and Panax ginseng aerial extract (leaf and stem) at line 12 of its 22-line blend. Root studies of Panax ginseng found a small fasting glucose drop and no A1C change. Eleuthero's blood sugar data come from animals. Label order caps the ginseng near 17 mg per dropper.

01Label facts
What does the label say about ginseng and eleuthero?
Two blend lines, neither with a printed amount.
The Supplement Facts panel names "Eleutherococcus Senticosus Root Extract" as line 5 and "Panax Ginseng Aerial Extract" as line 12. Both sit inside the 200 mg blend in each 1 mL dropper.
| On the label | In 1 mL | Studied at | Evidence | Watch for |
|---|---|---|---|---|
| Eleutherococcus Senticosus Root ExtractSiberian ginseng root | Blend line 5 of 22, share not disclosed | Small studies; blood sugar data are animal-only | Not established | Can raise digoxin levels. (MSKCC, Siberian Ginseng (Eleuthero)) (NIH ODS, Exercise & Athletic Performance) |
| Panax Ginseng Aerial ExtractAsian ginseng, leaf and stem (aerial parts) | Blend line 12 of 22, share not disclosed | About 100 mg to 20 g a day (mostly root) | Modest fasting-glucose drop; no A1C effect | May lower blood sugar; may affect blood thinners; insomnia. (NCCIH, Asian Ginseng) (Shishtar et al., PLoS One 2014) |
The roots in the top photo are a brand stock image. The label's ginseng is leaf and stem.
02Leaf or root
Why does the label say aerial ginseng and not root?
Aerial means the parts that grow above the soil. The brand poster still draws a root.
A plant extract is named for the part it comes from. "Aerial" points to the leaf and stem of Panax ginseng, which is Asian ginseng. The label does not say the root is used.
That matters. Most ginseng blood sugar trials tested root products (Shishtar et al., PLoS One 2014). No trial we know of shows a few milligrams of leaf extract doing what root did at far higher doses.
The brand's "Inside Glyco Harmony" poster adds to the mix-up. Its ginseng tile shows a forked root next to the words "Panax Ginseng Aerial Extract". The words are right. The picture is not what the label names.

03Research
What did ginseng trials find for fasting glucose and A1C?
A small fasting glucose drop, with wide differences between studies, and no clear effect on A1C.
A pooled review of 16 trials found fasting glucose about 5.6 mg/dL lower on average, with no clear A1C change (Shishtar et al., PLoS One 2014).
| Source | What it covered | Main finding |
|---|---|---|
| Pooled review, 2014 (Shishtar et al., PLoS One 2014) | 16 trials, 770 people, mostly root | Fasting glucose down about 5.6 mg/dL; no A1C effect |
| NCCIH, Asian ginseng (NCCIH, Asian Ginseng) | Diabetes research as a whole | Inconclusive and conflicting; a 2022 review of 20 studies saw fasting glucose gains |
| MSK, eleuthero (MSKCC, Siberian Ginseng (Eleuthero)) | Human and animal studies | Human data limited; blood sugar results come from animals only |
| NIH ODS, exercise (NIH ODS, Exercise & Athletic Performance) | Small performance studies | Little or no benefit from either herb; short-term use appears safe |
| NCCIH, diabetes supplements (NCCIH, Diabetes and Dietary Supplements) | All herbal products | No reliable evidence that any herb, ginseng included, controls diabetes |
04Blend math
How much ginseng or eleuthero can one dropper hold?
Not much. Label order sets a ceiling for each line, and neither ceiling reaches the trial doses.
Blend lines run from most to least by weight, which the label rules allow without single amounts (21 CFR 101.36 (eCFR)). So line 5 cannot weigh more than the four lines above it. Line 12 cannot weigh more than the eleven above it.
Those are upper limits. The real shares could be far lower. Even the ginseng ceiling is about a sixth of the smallest trial dose.
Two droppers double the ceilings to about 80 mg and 33 mg. The label stops there and says not to exceed it.
05Eleuthero
What is eleuthero, and how is it different from Panax ginseng?
Eleuthero is a different shrub, often sold as Siberian ginseng. It shares a plant family with Panax, not its research.
Eleutherococcus senticosus root
A woody shrub from northeast Asia. The label uses its root. Human studies are few, and any blood sugar findings come from animal work (MSKCC, Siberian Ginseng (Eleuthero)). Small exercise studies saw little or no gain (NIH ODS, Exercise & Athletic Performance).
Digoxin cautionPanax ginseng aerial parts
Asian ginseng, used here as leaf and stem. Its blood sugar research is the stronger of the two, though mostly on root and still modest (NCCIH, Asian Ginseng). Insomnia is the side effect people report most often. It may affect clotting.
Blood thinner cautionAds sometimes lend Panax results to eleuthero. They are separate plants with separate evidence. See the exact wording on the label explained page.

Who should be careful with ginseng and eleuthero?
People on diabetes medicine, blood thinners or digoxin, and anyone pregnant. Talk to a doctor or pharmacist first.
- Diabetes medicine. Ginseng might push glucose down, so it can add to insulin or a sulfonylurea (NCCIH, Asian Ginseng).
- Blood thinners. Ginseng may affect clotting and interact with some medicines, warfarin among the ones people ask about (NCCIH, Asian Ginseng).
- Digoxin. One case report found eleuthero raised digoxin levels. It may also make a digoxin blood test read falsely high (MSKCC, Siberian Ginseng (Eleuthero)).
- Pregnancy. Asian ginseng may be unsafe in pregnancy, and the label asks pregnant or nursing mothers to see a physician first (NCCIH, Asian Ginseng).
A low can show as shakiness, sweating, hunger, dizziness, confusion or a fast heartbeat. For many people with diabetes it means a reading under 70 mg/dL (NIDDK, Low Blood Glucose). Treat it the way your care team taught you. Fainting, a seizure or confusion that will not clear is a 911 call. More on the medicine and supplements guide.
07Our take
Are ginseng and eleuthero a good reason to buy Glyco Harmony?
Not on their own. They are small parts of a long list, at shares the research never tested.
Pros
- Panax ginseng has the most blood sugar research of any herb in the blend
- The label is honest that the ginseng is an aerial extract
- Both herbs appear safe for short-term use in studies
Cons
- Trials mostly used root, at 100 mg or far more
- Ginseng's share is at most about 17 mg per dropper
- Eleuthero has no human blood sugar data
A small effect from root at full doses does not carry over to a few milligrams of leaf. Weigh the whole formula on the claims vs evidence page.

08FAQ
Glyco Harmony questions people ask
Can I take ginseng with warfarin or another blood thinner?
Ask your doctor or pharmacist first. Asian ginseng may interfere with blood clotting and interact with some medicines, according to the NCCIH (NCCIH, Asian Ginseng). Glyco Harmony also lists guarana and coleus, which carry their own bleeding notes. Do not change your blood thinner dose on your own because of any supplement.
Does eleuthero affect digoxin levels?
It can. A case report found eleuthero raised blood digoxin levels, and it may also cause falsely high digoxin test results (MSKCC, Siberian Ginseng (Eleuthero)). If you take digoxin for your heart, check with your doctor before using any product with Eleutherococcus senticosus, Glyco Harmony included, and mention it before blood tests.
How much Panax ginseng is in one dropper of Glyco Harmony?
The label does not say. Ginseng is line 12 of a 200 mg blend listed by weight, so it cannot exceed about 17 mg per 1 mL dropper, and it may be much less. Ginseng trials used about 100 mg to 20 g a day, mostly root (Shishtar et al., PLoS One 2014).
Does eleuthero help blood sugar in people?
There is no human evidence for that. Memorial Sloan Kettering notes that blood sugar findings for eleuthero come only from animal studies, and human research overall is limited (MSKCC, Siberian Ginseng (Eleuthero)). Its place near the top of the Glyco Harmony blend does not change that. It is not a substitute for diabetes care.
Is ginseng safe to take while pregnant?
Probably not. The NCCIH says Asian ginseng may be unsafe in pregnancy (NCCIH, Asian Ginseng). The Glyco Harmony label also asks pregnant or nursing mothers to consult a physician before using it. Since the drops combine ginseng with caffeine herbs and licorice, talk with your prenatal care team before trying them.
Why does the Glyco Harmony poster show a ginseng root?
The poster is artwork. Its tile reads 'Panax Ginseng Aerial Extract', which means leaf and stem, but the picture is a root. Follow the label wording. The difference matters because most ginseng blood sugar trials tested root products, not leaf extracts (Shishtar et al., PLoS One 2014).
Can ginseng in Glyco Harmony cause a low with diabetes pills?
It might add to them. Ginseng may push glucose down, and the NCCIH advises people with diabetes to consult a provider before using it (NCCIH, Asian Ginseng). Combined with insulin or a sulfonylurea, that could raise the chance of a low. Check your levels and talk to your doctor before starting.
